SPRING-BED.

SPECIFICATION forming part of Letters Patent No. 632,412, dated September 5, 1899.

Application filed February 9,1898. Serial 110,669,694. N0 model.)

To all whom it Duty concern;

Be it known that I, FRANK H. I'IERTERICH, a resident of the city and county of New Haven, in the State of Connecticut, have invented a new and useful Improvement in Spring- Beds, of which the following is a full, clear, and exact description when taken in connection with the accompanying drawings, which form a part hereof, and in which-- Figure 1 represents a plan view of a springbed embodying my invention; Fig. 2, a crosssection on lines 2 2 of Fig. 1; Fig. 3, an enlarged detail plan view of the meeting ends of the slats and connections therewith, and Fig. 4 a similar detail view in elevation.

In all figures similar letters of reference represent like parts.

This invention relates to spring-beds, and more particularly to spring-beds having spiral springs and adapted for use with iron bedsteads.

The invention consists in the improvements and novel combinations of parts set forth and claimed hereinafter.

In the drawings the parts marked with the letter A represent metal hooks,the upper ends of which, a, are adapted to fit over the sides of an iron bedstead. The lower ends a are turned lengthwise, as shown in Figs. 1 and 2, so that the plane of the metal comprising this end is at right angles to that of the remainder of the hook.

Rigidly secured to the lower ends a of the hooks are slats B and B, the plane of which is vertical, like that of the ends a of the hook, so that any article resting on the slats when in position bears on the edges of the slats. As the slats do not extend across the width of the bed, but are merely slightly longer than one-half this width, the inner ends of the I slats B overlap theinner ends of slats B, as

shown in detail in Fig. 3. At the inner end of each slat B or B is formed a flanged way or groove 1) or b", which embraces the overlap ping slat B or B, at the same time allowing it a longitudinal sliding movement therein. By this means the slats are adapted to be shortened or extended across the bed, as desired, while to strengthen the central portion two strips or braces C and C are provided,extending lengthwise with the bedstead, one, C, be-

ing rigidly secured to the inner end ofthe slats B and the other, C, to the inner ends of the slats B. I

Mounted on the slats Band B is a bottom formed extensible in the following manner A series of parallel bars or strips E and E extend lengthwise with the bedstead and across the slats B and B, on which they rest. The two outer strips E are rigidly mounted on the ends of the slats B and B adjacent to thehooks A and move with the slats; but the remaining strips E are independent of the slats. The ends of the strips E and E are connected by diagonal bars F and F, which cross each other and are pivoted together at their meeting-points f, f, and f to form a lazy-tongs connection between the strips E and E. The outer ends of the cross-bars F and F are also pivoted at f to the outer ends of the strips E and E, while at the inner ends of 'thecrossbars the pivot f extends through and is guidedin its motion by a slot 6 in the strips E or E.

Spiral springs H are mounted on the strips E or E and are connected by links or chains h with one another and with two bars I, which extend lengthwise along the sides of the bedstead at substantially the height of the top -of the springs, being held in place by braces formed of .two connectingbars'K or K. The bars K are rigidly connected to the outer strips E and project inwardly a short distance, as shown in Figs. 1 and 2. At their inner ends are secured the bars K, which extend to and are connected with the bars I, and by this connection the bars I are allowed a certain freedom of movement to correspond with any movement of the springs H.

A further feature of the invention is a flange L, which may be formed with or secured to the ends of the metal ways I) and b and is adapted to extend downwardly to the edges of the slats B and B, so that when the bed is contracted the strips E and E will ride up on the flanges L over the ways I) and b, and thus the strips be prevented from striking against IOO rigidly secured to the outer ends of the slats the spring-bottom is contracted or folded by means of the lazy-tongs connection between the ends of the stripsE and E.

By this construction a light spring-bed is produced,which is strengthened by the slats, and the whole device is capable of being extended or contracted, as desired. r

Having now described my invention, which may vary somewhat without departing from the spirit thereof, what I claim, and desire to secure by Letters Patent, is

1. In a spring-bed the combination with series of slats less in length than the width of the bed and adapted to be suspendedfrom the bed with their edges uppermost,the slats on the opposite sides overlapping and having'a sliding connection with each other; of strengthening bars or braces secured to the under side of the ends of the slats; of a bedbottom provided with a series of parallel strips of metal adapted to extend across and rest on said slats and carrying springs, two of-said strips being rigidly secured to said slats and all having a lazy-tongs connection with each other by which they may be forced together or apart as said slats are moved on each other, substantially as described. 7

2. Ina spring-bed the combination with an extensible and contractible bed-bottom carrying spiral springs of slats of less length than the width of the bed, the slats on opposite sides overlapping each other and having metal ways in which the opposing slats may slide, said bed-bottom being secured to said slats so that it will be contracted or extended as said slats are moved on each other; and inclined or beveled flanges on said ways to guide the bed-bottom in its movement, substantially as described. I

In witness whereof I have hereunto set my hand this 8th day of February, A. D1898.
